SPEOIFIGATION forming part of Letters Patent No. 272,196, dated February 13, 1883.

vApplication filed August 18, 1882. (No model.)

To all whom 'it may concern:

Be it known that we, CORNELIUS BIRKERY and HENRY SLORD. of Hartford,in the county of Hartford and State of Connecticut, have in vented a new Improvement in Water-Closet Valves; and we do hereby declare the following, when taken in connection with accompanying drawing and the letters ot' reference marked thereon, to be a full, clear, and exact 1o description ofthe same, and which said drawing constitutes part of this speciiication, and

represents a vertical central section.

This invention relates to an improvementin that class of valves for water-closets which is x5 designed to operate automatically to regulate the i'low or quantity of water admitted to the bowl for iiusling purposes-that is to say, the quantity or time of the tlow after the bowl shall have been opened and closed-and par- 2o tieularly to that class which employs a valve hung to a diaphragm, with a small aperture through the water-way to a chamber on the side ot' the diaphragm opposite the valve, so astoproduee an equilibrium on the diaphragm,

which closes the valve. Then when that equilibrium is removed, by permitting` the water on the said opposite side of the diaphragm to escape, the valvey opens for a large flow of water to the bowl, a very small portion of the water 3o escaping to the opposite side ofthe diaphragm until this small quantity has produced the equilibrium to close the valve. The time of- 'liow of water to the bowl is therefore thetime between breaking and restoring the equilibrium. Usually a valve has been employed in the waste-passage from the chamber on the opposite side of the diaphragm to close the escape, and thereby reproduce the equilibrium. This valve isnecessarily small and liable to 4o be choked by foreign substances in the water, which will prevent the valve from perfectly closing, and which will prevent the restoring of the equilibrium, because the small'quantity of water admitted to thatside of the diaphragm escapes.

The object ot' our invention is to overcome this ditiiculty; and the invention consists in the arrangement of a water-chamber or combined air and water chamber, in connection with the chamber on that side of the dia.- 5e phragm opposite the valve, combined with a valve in said chamber, in connection with the pull which opens the iiow from the bowl, whereb v the water in said water-chamber will beinstantly discharged and break the equilibrium 55 to cause the tlow of water to the bowl. The passage from the chamber closed when the pull is dropped, the equilibrium will be restored by the dow oi' water through the diaphragm into said waterchamber, as more fully hereinafter 6o described.

A represents the inow water-passage, and B the outflow to the bowl. The outflow-passage is closed by a valve, YC, hung to a diaphragm,D,whichfornisachamber,E,ontheside opposite the valve. Through the diaphragm.or valve-stein, which is the same thing, is a small wate1-passage,a, very much less in extentthan the openingthrough the valve-seat into thepassage Hence, when the valve C is raised, 7o water flows freely through the passage A and passage B to the bowl, a portion ot' it escaping through the small passage a to the opposite side ofthe diaphragm, and so that if the outflow from the chamber E above the diaphragm be arrested that chamber will be graduallymlled by the water liowing through the passagec until an equilibrium is produced, when'the valve will be closed. The valve C is again opened by breaking that equilibrium. 8o This is a Well-known valve arrangement for vwater-closets.

From the chamber E is an eseapepassage, F, forthe water from that chamber E, for the purpose of breaking the equilibrium. It is in S5 r this passage that the small stopvalve has heref tofore been arranged. Instead of employing such a valve, we arrange a water-chamber, G, in size corresponding to the amount of Water which may flow through the aperture a in the 9o time fixed for the proper iiushing or flow of water to the bowl.

1n the lower part of the chamber G is a valve, H, which l'ts closely upon a seat, and in connection with the lever which operates the g5 pan of the bowl or opens the wasteway in connection therewith, so that when the pull is drawn up, as in broken lines, it will raise the valve H, butwhen the pull is dropped the valve H will be drawn to its seat. Below the valve H is a wasteway, b, for the water which may tiow from the chamber G when the valve is opened.

To illustrate the operation of our invention,

suppose the valve C to be closed, the waterchamber G and the chamber above the diaphragm to be lled with water, so as to produce the required equilibrium to hold the valve O closed. Then when the pull is drawn up, or the wasteway from the closet opened, the valve H will be raised, openingr a large passage for lthe escape ot' the water from the chamberG. lhisrapidescapeinstantlybreaks the equilibrium, and the valve C rises to open the flow to the bowl, and also through the small aperture a to the chamber G. This flow through the chamber G will continue so long as the waste from the bowl is held open and until the valve H is closed. So soon as the pull is dropped or the wasteway closed the valve H drops upon its seat and closes the escape from thechamber G. The tlow will then continue through the passage to the bowl, and through the passage a, until the water-chamber G and the chamber above the diaphragm are iilled to the water-pressure. Then the eqni librinm will be restored and the valve U closed. The time in which the iow to the bowl will be continued after the pull is dropped or wasteway closed will depend upon the size of the chamber G. It' that be smaller, the time will be shorter, but it it be greater the time will be longer. The time may therefore be regnlated by applying dit'erent-sized chambers G, or the chamber itself may be made adjustable, or passage into the chamber G. In order to avoid the water-hammer, the discharge F is continued into the chamber and down toward the bottom, as at d, so that the discharge into the chamber G will be below its highest point. So soon, then, as the water has risen in the chamber G to the end of the discharge d, from that time the air in thehamber G above the surface of the water will be gradually1 compressed and form an air-cushion upon the water, which will check the so sudden closing ot' the valve as to produce what is called water-hainnier,7 or return of air in the chamber through the water, so as to produce gnrgling This chamber G then serves the double purpose of regulating the flow of water to the bowl, and also as an air-chamber to prevent water-hammer.

While we have described the opening ofthe wasteway as by a pull, yet any of the known devices for opening the flow may beemployed, it only being essential that such devices shall be connected t0 the valve H, so that in opening the flow from the closet it will also open the valve H.

Instead ofthe diaphragm, any of the known valves which operate upon this principle of producing an equilibrium by a small passage from the valve-chamber to a point opposite the valve, so as to produce an equilibrium, may be employed. We therefore do not limit our invention to this particular construction of water-closet valve. The device for operating the valve in the water-chamber should be 0perated at the same time as the pull-up or opening of the waste-valve. Hence we connect them together, or so arrange them that they may be conveniently operated at or about the same time; butthey may be independent cach of the other. By the term connectiom as herein used, between the two, we therefore wish to be understood as meaning that there shall be a device for operating both the flow or pull and the valve in the water-chamber; but they may be independent one of the other.

We claim- 1. In an apparatus for flushing water-closets, the combination of a valve arranged to close the passage to the basin, a water-way leading from the supply onto the said valve, a chamber, E, above lthe said valve, the said waterway constructed with an aperture leading to said chamber E, said aperture being considerably smaller than the said water-way, with a water-chamber, G, in connection with the said chamber E, and a valve arranged t0 open the waste-passage from said waterchamber G, and mechanism, substantially such as described, to open said water-chamber valve, substantially as specified.

2. In an apparatus fortiushingwater-closets, the combination of a valve arranged to close the passage to the basin, a water-way leading from the supply onto the said valve, a cha-m- CORNELIUS BlRKERY. HENRY S. LORD.
